Q. What are diseases of the thyroid gland?
Doctor Answer is medically reviewed by SecondMedic medical review team.
The thyroid gland is a small, butterfly-shaped gland located in the front of your neck, and it plays a big role in regulating your body's metabolism. Like any other part of your body, it can be prone to diseases. Here are some common thyroid diseases:
1. Hypothyroidism: This occurs when your thyroid gland doesn't produce enough thyroid hormone. Symptoms can include fatigue, weight gain, cold sensitivity, dry skin, and constipation. The most common cause is an autoimmune condition called Hashimoto's thyroiditis, where your immune system attacks the thyroid gland.
2. Hyperthyroidism: This is the opposite of hypothyroidism, where your thyroid gland produces too much thyroid hormone. Symptoms may include weight loss, rapid heartbeat, sweating, nervousness, and heat intolerance. The most common cause is an autoimmune disorder called Graves' disease, where the immune system stimulates the thyroid to produce too much hormone.
3. Thyroid nodules: These are lumps or growths in the thyroid gland. Most thyroid nodules are benign, meaning they are not cancerous. However, some nodules can be cancerous. Often, thyroid nodules don't cause any symptoms, but they can sometimes cause difficulty swallowing, hoarseness, or a visible lump in the neck.
4. Thyroiditis: This is inflammation of the thyroid gland. There are different types of thyroiditis, including Hashimoto's thyroiditis (mentioned earlier) and subacute thyroiditis, which can be caused by a viral infection. Symptoms can vary depending on the type of thyroiditis but may include neck pain, fever, and fatigue.
5. Thyroid cancer: Thyroid cancer is relatively rare compared to other types of cancer but can still occur. It usually presents as a lump or nodule in the thyroid gland. The most common types of thyroid cancer are papillary and follicular thyroid cancer. Treatment often involves surgery to remove the cancerous tissue, sometimes followed by radioactive iodine therapy or other treatments.
6. Thyroid dysfunction during pregnancy: Pregnancy can sometimes affect thyroid function. This includes conditions like gestational hypothyroidism or hyperthyroidism, which can affect both the mother and the developing baby if left untreated.
These are just a few examples of thyroid diseases. If you suspect you have a thyroid problem, it's important to see a healthcare professional for evaluation and proper management. Treatment for thyroid diseases can vary depending on the specific condition and its severity, but options may include medication, radioactive iodine therapy, surgery, or hormone replacement therapy.
